Connect you with others on TikTok


When you add your phone number to your account, we can connect you to others on TikTok. There are 2 ways to connect you with others: by suggesting your account to others, and by suggesting accounts for you to follow.

Suggest your account to others using contacts
When the Contacts setting in the Suggest your account to others section is on, your account may be suggested to someone else on TikTok if you've added your phone number to your TikTok account, and the person we're suggesting your account to has chosen to sync their phone contacts to TikTok and your phone number is in their contacts. Learn more about how your phone number is used to suggest your account.

To review and change the Contacts setting:
1. Tap Profile in the bottom right.
2. Tap the 3-line icon in the top right to go to your settings.
3. Tap Settings and Privacy.
4. Tap Privacy, then tap Suggest your account to others.
5. Tap the toggle icon next to Contacts.

Accounts we suggest to you with your phone contacts
We can also help you find and follow people you may know if you've added your phone number and your phone contacts are synced. You can stop syncing at any time and remove any previously synced data from TikTok.

To review and change your Sync Contacts setting:
1. Tap Profile in the bottom right.
2. Tap the 3-line icon in the top right to go to your settings.
3. Tap Settings and Privacy.
4. Tap Privacy, then tap Sync contacts and Facebook friends.
5. Tap the toggle icon next to Sync contacts to turn on or off. You can also remove previously synced data.
